Loki, the outsider in the Northern Germanic pantheon, confounds not only his fellow deities and chronicler Snorri Sturluson [referring to the Prose Edda] but has occasioned as much quarrel among his interpreters. Hardly a monograph, article, or encyclopedic entry does not begin with the reference to Loki as a staggeringly complex, confusing, and ambivalent figure who has been the catalyst of countless unresolved scholarly controversies and has elicited more problems than solutions.
